This invention relates'to reenforced hose and particularly to hosedesigned for heavy and severe duty.

The invention has been 5 out in pressure pulsates use to vibratecontinuously. Itwill be obvious that the invention will appear from thefollowing specification taken in connection with the drawing, whichforms a part of is application, and in which Fig. 1 is an elevationalview broken away to show the different sections or layers of the hose;el and Fig. 2 is a transverse sectional elevation of the hose shown inFig. 1.

The invention briefly described consists of a hose comprising aplurality of concentric layers 40 of material intimately united to forma unitary st The body rubber or rubber-like d arranged for he body ofthe ayers of reenforcing material are inand is wound tightly aroundlayer in a spiral path,

case two layers of material are used, one

layer is wound in a spiral ection with a reenforced hose for use- N.York Rubber Gorporation, corporation of New York Application March6,1929, Serial Y., assignor to New New'York, N. Y., a

344,651 Cl. 138-56) I in one direction tions to cross When the hose ismade up in the manner above described, it is vulcanized under pressure,and the rubber in the layers D and F will flow into and completely fillthe interstices in the mesh of the wire strips. This effectivelycounteracts any tendency of the wire strips to unwind and, furthermore,prevents the wire and adjacent parts from separating. v It will beobvious that the reenforcing layers C and E'will counteract any tendencyof the hose to stretch and the elasticity of the rubber and of thereenforcing layers will permit the hose to bend or twist but will returnthe hose to its original shape after the bending or twisting stresseshave been removed. As many reenforcing layers can be used as isdesirable and it is not the intention to limit the invention to anyparticular number of reenforcing layers.

Moreover, the invention is not limited to the use of wire mesh material,but is intended to include in its broader aspects the use of strips orribbons of other metallic material constructed and arrangedforinterlocking engagement or intimate union with the rubber-like body ofthe ose.

Although the reenforced hose has been particularly described inconnection with oil drilling operations, it should be understood thatthe invention is not limited to anysuch specific use but is capable ofgeneral application and the hose may be used wherever .necessityrequires a hose capable of withstanding severe usage.

Although one specific embodiment of the invention has been particularlyshown and dethe invention is capable of modification and that changes inthe arrangement of the parts maybe made without departing from thespirit or scope of the invention, as expressed in the following claims.

What I claim is:

terial having embedded therein a plurality of separated spirally woundlayers of mesh material, the convolutions of which are slightly spaced,one of the layers being wound in one direction and another layer beingwound in the opposite direction.

2. A hose comprising a body of rubber-like material, and a plurality ofreenforcing meshstrips embedded therein, said strip being of flexiblematerial, the material on opposite sides of such strips being unitedthrough the spaces therebetween, said strips being wound in oppositedireceach other, and each strip having slightly spaced adjacentconvolutions constructed and arranged to permit bending of the hosewithout causing saidadjacent convolutions to abut or overlap.

- 3. A hose comprising a body of rubber-like material and having a ofspirally wound layers, said layers being wound in opposite directionswhereby the convolutions cross each other and at least one of saidlayers being formed of metallic mesh material and being embedded in 4. Ahose comprising a body of rubber-like material, and a plurality ofslightly spaced convolutions of reeniorcing mesh strips embeddedtherein, said convolutions crossing and being of flexible material, thematerial on opposite sides of such mesh strips being united through thespaces therebetween.

5. A hose comprising a body of rubber-like ma- 1. A hose comprising abody of rubber-like mahand helices,

terial having .embedded therein a plurality of separated spirally woundlayers of metallic mesh material, said layers being wound in oppositedirections to cross each other, and each layer having the adjacentconvolutions slightly spaced to permit bending of the hose withoutcausing said adjacent convolutions to abut or overlap.

6. A hose comprising a body of rubber-like ma- .terial having embeddedtherein a plurality of layers of foraminous metallic reenforcingmaterial, said layers being woundin opposite directions to crosseachother, and each layer having adjacent convolutions spaced apart topermit bending of the hose without causing said convolutions to abut oroverlap.

7. A hose comprising a body of rubber-like material and a plurality ofreenforcing mesh strips embedded therein, said strips being of flexiblematerial, the material on opposite sides of such strips being unitedthrough the spaces therebetween and. through the openings in said mesh,said strips being wound in opposite directions to cross each other, andeach layer-having slightly spaced adjacent convolutions to permitbending of the hose without causing said convolutions to abut oroverlap.

8. A hose comprising a body of rubber-like material having imbeddedtherein a plurality of separated spirally wound layers of metallic meshmaterial, one of the layers being-wound in one direction and anotherlayer being wound in the opposite direction.

9. A hose of the character described, including a tubular wall structurehaving therein a plurality of rubber saturated flat metal fabric ribbonswound one outside the other in opposite hand helices;

10. A hose of the character described, including a rubberized tubularwall structure having a plurality of rubber saturated fiat metal fabricribbons wound one outside the other in opposite the rubber of saidribbons being combined with the rubber of said tubular wall structureinto a homogeneous rubber structure during curing of the hose.

11. A hose of the character described, including: an inner tubularrubber wall; an intermediate cloth fabric wall surrounding said innerwall; crossing helices of flat rubberized metallic fabric ribbon woundon said, cloth fabric; and an outer layer of rubber covering thepreviously set forth structure, the rubber of the various layers'beingamalgamated into a homogeneous rubber structure when cured afterplacement of the layers in their relative positions.

12. A hose comprising an inner tube of rubber, a tube of woven fibrousmaterial surrounding said rubber tube, a tube formed of spirally woundwire braid forming a substantially continuous covering over said tube offibrous material and in such relation thereto as to afford it asupporting pressure before any inner layer is stretched radially to itselasticlimit, and a second tube formed of wire braid wound on a spiralwhich is oppositely inclined from the first named spiral of wire braidwith respect to a plane perpendicular to the axis of the tube and whichis in such relation to the layer within it and is so positioned in thebody of the hose as to exerta supporting pressure thorcagainst beforeany'inner layer is stretched radially to its elastic limit.

13. A hose as defined in claim 12 in whichthe threads of the wovenmaterial and the wires of the spiral braid are embedded in a matrix ofvulcanized rubber.
